Hours before their teammates headed to Seattle, injured outfielder Fernando Martinez and injured lefthander Travis Blackley packed their bags for a flight to Orlando, Fla., for extended spring training.

Martinez and Blackley will continue their rehab at Osceola County Stadium in Kissimmee, Fla.

“I’m going to start to swing tomorrow,” said Martinez, who is on the 15-day disabled list with a strained oblique muscle. “Hopefully, by the end of the week, I can start playing (games).”

Blackley was placed on the 15-day disabled list Friday with a left shoulder strain one day after he was acquired from Oakland.

“We’re going to go back down to Florida and get it going back strong,” Blackley said.

Both hope to get work in during extended spring training before joining Class AAA Oklahoma City for rehab assignments perhaps as early as next week.

“The biggest thing you want them to do is get healthy, because a healthy Fernando Martinez can help our ballclub,” manager Bo Porter said. “A healthy Blackley will help our bullpen as well. We want those guys to go down there and get their rehab, get themselves healthy and get back here as soon as possible.”

Blackley is optimistic about rejoining the club.

“All things going well, I should be back here in like 13 days or so because I was retroactive to Friday,” he said. “That’s my goal anyway. I want to be here as soon as I can. I’m just ready to get this season going and get the rhythm going and do what I can.”

Carter triples in DH role

Chris Carter served as designated hitter for the first time Sunday.

He was 1-for-3 with a walk, a run and his first career triple.

Castro gets a day off

Partly because of the day game after a night game, Carlos Corporan started behind the plate, while regular starter Jason Castro was out of the starting lineup for the first time this season.

Castro had served as DH on Tuesday when Corporan started for the first time this season.

Keuchel endures long travel day

Reliever Dallas Keuchel, who pitched a scoreless inning Saturday hours after arriving from Memphis, was happy to get a good night’s sleep after a long day of travel.

Keuchel was at his hotel Friday night close to midnight when he learned he had been called back up from Class AAA Oklahoma City. His equipment was packed in the clubhouse and brought to his room.

He arrived in time for his noon flight to Houston, but airport delays caused a late departure.

“My flight was supposed to be at 12 p.m., but I ended up leaving at 2:45 p.m.,” he said. “I was at the airport all day. The excitement of being back got me through.”

Blue Jays pick up Gonzalez

The Blue Jays claimed righthanded reliever Edgar Gonzalez off waivers from the Astros on Sunday.

The Astros designated Gonzalez for assignment Friday, one day after they acquired Travis Blackley from the Oakland A’s.
